Go to this url ==>
http://www.mingw.org/wiki/Getting_StartedClick the link that says "Download and run the latest mingw-get-inst version."
Download and run the latest file.
Install MinGW in the default directory.
(I downloaded the one labeled "mingw-get-inst-20120426" - note that this could
be a different version later.)
Make sure to check the option for "Download latest repository catalogs".
I selected all the check boxes (excluding "Fortran Compiler") so that everything
was installed.
